从 Kapsel 离线应用程序在 OData V2 模型上进行 SAPUI5 深度插入

Question

Question:

How can a "Deep Insert" performed from a SAPUI5 Client application on an OData V2 Model?

Situation:

I want to Deep Insert an "Operation" together with some "Components" into my OData V2 Model in my SAPUI5 Client application.

 // the request data
 "OperationSet" : {         
          "Orderid" : "13700090",       
          "OperationComponentSet" : [
              {                
                "Orderid" : "13700090",
                "Activity" : "0010",
                "SubActivity" : "",
                "ComponentItem" : "000010"                 
              }
            ]
}

this.getView().getModel().create("/OperationSet", requestData);

I cannot use the function create(sPath, oData, mParameters?) on the OData V2 Model the documentation says: "Please note that deep creates are not supported and may not work." see https://sapui5.netweaver.ondemand.com/sdk/docs/api/symbols/sap.ui.model.odata.v2.ODataModel.html#create

Is there any other possibility to perform a Deep Insert on an OData V2 Model?

Answer 1

The answer is, "Deep Insert" doesn't support 0..n assoziations with the Offline Kapsel Plugin at the moment.

see http://help.sap.com/saphelp_smp308sdk/helpdata/en/d3/0ded03756247f1a136c84be7901879/content.htm

Limitations of Deep Inserts A deep insert is an OData POST request to create an entity that also contains the inlined definitions of related entities.

When a deep insert is processed, the top-level entity and all of its related entities are created and linked together as a single operation. In SDK SP07, the Offline Store supports deep inserts through the OData API on Android, iOS and WinPhone 8 platforms with one important restriction:

• The navigation property used for the deep insert must refer to at most one entity. Any inlined related entities must be added using a navigation property whose ToRole refers to an association end with cardinality 0..1 or 1. They cannot be added using a navigation property whose ToRole refers to an association end with cardinality *. Navigation properties that refer to a set of entities cannot be used for deep inserts.

So "Deep Insert" will only work if the request is executed online against the gateway at the moment.
